I want to run these at 12V with 3 LEDs connected to a single chip. I need 5V zener diode + filter cap as datasheet says to make chip work on 12v.
What about R/G/B feedback pins: are resistors on them a must? If no resistors, current is not limited and I should be careful not to exceed max. output current? Should I connect them to ground or leave them float?
Also, the LEDs. Can I connect them in series although datasheet says max. output is 7V? Will brightness be lower? I have seen some strips with three LEDs in series including current limiting resistors on them connected to a ws2801. How that works?!?
Thanks :)
